We are new Tracer owners ~ only one campout so far, but we have had several campers over the last 15 years. We have a 2011 2905RK Executive Series.
What we like ~ Reasonably good quality build, seems like a midlevel camper to us, which fit our budget nicely. Ours has the power jacks, both front and stablizer; power awning, double slide, and appliances (AC, etc) that seem to work well in our unit. There is a gas hose for a grill to be used outside. The storage space outside is sufficient and DH likes the way the water, etc is enclosed at the hook up site.
What we wish were better ~ I really wanted an outdoor kitchen and this model has none. It also doesn't have a grill that attaches to the outdoor wall for cooking like so many units have. The storage space (cabinets) inside is not optimal and could have been designed much better both in the bath and kitchen.
Overall, we are happy with our camper and feel good about our purchase and the deal we got when we bought it. The items that we wish were different are workable for us so we don't consider them too big of a deal. We looked at Keystone too, and found a unit I really liked but DH wasn't as keen on, the outside looked like it had been baked in the sun and had not held up nearly as well as the Tracer's had. The particular unit we saw also was obviously a lower end unit in the interior finishes, however it really appealed to me. We could have had the exterior worked on and brought up to snuff, but the deal just wasn't there for that unit, so....... the rest is history.
Good luck with your endeavor~~~
